I agree it looks like its not really a big deal; what I cant find is what
changed to make this even print out. The commits for this warning are from
a long time ago. Off hand they are from 2014 or 2012. There were no changes
to sys/dev/random in as much time; so I cant figure out what changed to
make this even print out.
